Above the oceans once before
The Concorde flew its route routine
A super sonic transport expedient
The Vietnam War, its costly demise
For a country unwilling to bear it
The costs of pollution and fuel too
Remanded to static displays bygone
The world made smaller, shorter
Destinations brief at mach two
Lo, the sonic boom adversity
That sullied speed in Urbana
For trembling, rattling terror
Of those on the ground below it
An 'N' wave that could not go
Configured by the aircraft's ply
Now relegated to past dreams
Prospect of mach four and more
Inspiring presence with a boom
